This comparison is a continuation of: https://www.dpreview.com/forums/post/67379972

Cameras:

• Panasonic G9.m2 [firmware 1.0]

Lens used: Voigtlander 40mm F1.4 NOKTON Classic (L/M mount converted to MFT)

Shutter speed: 1/200

Aperture: F1.4

ISO - Manually set for each camera identified above.

Disclaimer, these are my observations based on the images present in all 3 forums I posted in based upon the JPEGs. Both camera JPEG settings are camera default. Once I have access to the RAW files I can update further... waiting on DxO Photolabs.

Image detail

G9.m2 provides very-very slightly more detail in the images. You need to pixel peep to really notice the difference. I expected better performance for additional 5MP (20%) increase.

Image darkness

The G9.m2 images are darker, the OM-1 are more true to naked eye. I am assuming this is because the difference in base ISO. The Panasonic uses a base ISO of 100 while the OMDS uses 200 as its base ISO. The user will need to compensate/correct for this with the Panasonic.

High ISO performance

The OM-1 handles color noise cleaner.

Focusing

Neither camera had any issue auto-focusing during any of my testing (excluding the Voigtlander lenses as they are manual with no contact points) .

Will look forward to these processed from RAW with identical, standard profiles in RAW convert. As I mentioned to you, I’d be glad to do a few in ACR, if you wanted to see them now.

There are too many variables in jpeg processing, based on what the mfg selects as defaults and what we can adjust. For example, base picture profile, noise reduction & sharpen settings, saturation, contrast, etc. obviously, it is the same as processing in a raw converter, but, for example, in ACR one could chose the common ‘Adobe Standard’ and hold all other settings the same. Even then, slight differences will probably be present…which is why we all must test and understand how our cameras will perform in different situations.

And if you get access to the raws (with ikolbyi's permission, of course), it would be great if you could save them from ACR as DNGs and make those downloadable for those of us stuck on older versions of ACR/PS.

Yes, trying to do any kind of careful analysis based on the the camera makers' proprietary JPEG engines is next to useless for understanding what's going on at the raw level.

I was able to 'hack' Photoshop version 21 to accept/install CameraRAW version 16 which has the G9.m2 RAW profiles. Photoshop version 21 only officially supports CameraRAW version 14.4 which does not support any 2023+ camera.

DPReview would not allow me to upload TIFF or PNG conversions due to the 100mb file sizes they generated.

These images are the RAW images converted using Adobe Photoshop CameraRAW into JPEGs quality level 12.

So far what you are showing corroborate what Chris and Jordan's comparative review said.

While I wait for DxO (my primary RAW editor) to release the G9.m2 modules, I process the images from my original 2 posts through CameraRAW to see how Adobe treats the files. To my surprise, the G9.m2 look better to me through Adobe's engine compared to in camera processing.

I used CameraRAW AUTO processing features to generate these files.

I own 1 more camera that fills a very specific roll and doesn't see much use: Sony a6300. It exclusively uses only 2 lenses:

• Voiglander 40mm F1.4 NOKTON Classic (L/M mount)
• Voigtlander 90mm F2.8 APO-Skopar (L/M mount)

These are the same subject sample photos in comparison: older APSC Sony sensor vs modern MFT. I'm including it just in case individuals are interested in how the OM-1 & G9.m2 compares to an older APSC Sony camera.
